BOAT CONSTRUCTION.

Specification of Letters Patent. Patented lflay 2'7, 1919,

Application filed August 2, 1918. Serial N 0. 248,036.

To all whom it may concern.

Be it known that I, EZRA KELLER FAILoR, a citizen of the United States,and a resident of Springfield, in the county of Greene and State ofMissouri, have invented certain new and useful Improvements in Boatconstrue tions, of which the following is a specification.

My invention is an improvement in boat constructions, and has for itsobject to pro: vide a construction of the character specified, whereinis obtained a combination of speed, stability and capacity, withlessened draft and widened beam.

A further object of the invention is to provide a construction havinggreat rigidity, and wherein twin or triple screws may be provided, andwithout outboard mountings for the propeller shaft.

A further object of the invention is to provide a construction whereinhydroplanes may be used without affecting the fine side lines, andwherein a plurallty of centerboards may be used, if desired.

In the drawin s:

Figure 1 is a bottom plan viewof a boat constructed in accordance withthe invention;

2 is a longitudinal section;

Fig. 3 is a section on the line 33 of Fig. 2, looking in the directionof the arrows adjacent to the line.

In the embodiment of the invention shown, two keels 1 are provided, thesaid keels being laid in the usual manner, and having connectedtherewith the usual stem and stern posts 2 and 3. The usual framing 4:is connected wit-h each keel at the outer side thereof, and this framingis covered by the usual planking, indicated at 5. Two half hulls arethus formed, each having a keel and stern posts, and these half hullsare connected by a truss construction indicated at 6.

Planking 7 completes the hull, the planking extending between the keelsas shown,

and it will be obvious that this portion of the boat between the halfhulls .and which connects the half hulls may be of any suitable ordesired width, thus providing for any desired capacity, withoutmaterially increasing the draft.

Double propellers, indicated at 8, may be used, the said propellersbeing connected with the usual shafts and driven by any preferred formof motor, indicated at 9. There are no outboard mountings for thepropellers and hence no drag from such mountings. The interior of thecompleted hull may be sub-divided in any suitable or desired manner, as,for instance, by bulkheads, and two center boards may be used ifdesired. It will be evident that that portion of the hull indi cated at7 and lying between the keels might be made up of a series ofhydroplanesif desired, thus securing great speed without sacrificing the fine sideline of the hull. Two center boards may be used if desired, thusproviding for greatly increased sail capacity in sailing vessels.

The invention in its broadest form consists of half hulls spaced apartand rigidly connected by an intermediate or central hull section.

It will be understood that the framing 4 connected with the keels mayextend across between the keels if desired, and the truss constructionwill be in accordance with the size of the vessel. As many centerboardsand propellers may be used as may be necessary or desirable.

I claim:

In a boat construction, a hull composed of a mid section and lateralsections, the lateral sections being half hull sections, and each havinga keel, a stemand a stern post, the half sections being arranged inspaced rela tion, a truss connection between the half sections, thespace between the hulls being sheathed to provide water tight cargospace,

and said sheathing having a greater inclination at its ends than at theends of the half sections.
